Answer:
Each box of two inch nails contained 67 nails
Explanation:
Givens
291 one inch nails
5 boxes of 2 inch nails
Total number of nails = 626 nails
Formula
291 + 5*two = 626 Two is the number of 2" nails in one box
Solution
291 + 5*two = 626 Subtract 291 from both sides.
5*two = 626 -291 Combine
5*two = 335 Divide both sides by 5
5*two/5 = 335/5
two = 67
